Does anyone know off the top of their head what the cost of Sea Bands are in US? I saw some at Walmart here in Toronto, and they were $13.33 Cdn which would be about $9.00 US...is this about what you can get them for in US? I plan to get them for me as I'm prone to motion sickness, but has anyone used them with their children...do they work? I have no idea how my children will do if there are rough seas, but want to be prepared just in case. Any thoughts on "drugs/gravol" vs sea-bands? Thanks, Jo
